SLIDING' SCREEN, DOOR, 86C.

SPECIFICATION forming part .of Letters Patent No. 451,631, dated May 5,1891.

' Application tiled April 28, 1.890.' Serial No. 349,728. (No model.)

To all whom t may concern:

Be it known that I, CLARENCE B. BISHOP, a citizen of the United States,residing at Chicago, Cook county, Illinois, have invented a new anduseful Improvement in Sliding Screens, Doors, dac., of which thefollowing is a specification.

It is often desirable or even essential that sliding screens, windows,doors, and similar io structures should be capable of being openedoutward or inward as thoughhungupon hinges like a door or gate; and itis the object of my invention to provide means whereby screens, doors,dac., may be thus opened while still remaining capable of sliding up anddown upon or in guides or ways; and the invention consists in thefeatures and details of construction hereinafter described and claimed.

I shall illustrate and describe in the drawings and specification andalso claim in the claims hereof my improvement as applied to awindow-screen; but Idesire it be definitely understood that I do thissimply for the sake of brevity and convenience,l andnot with theAintention of limiting myself to this use alone, sinceI am fully awarethat the devices hereinafter described may be applied with equalefiiciency to a sliding door, window, or similar structure,and Icontemplate so applying them.

In the drawings, Figure l represents a vertical exterior elevation of awindow provided with one of my improved screens; Fig. 2, a horizontalsection o n the line 2 2 of Fig. l, looking in the direction of thearrows, the position of the screen when open being indicated in dottedlines; Fig. 3, a central section through vthe upper left-hand corner ofthe screen, showing the construction of one of the spring-hooks; Fig. 4,a perspective view of one of the eyes or sockets, the strip on which thescreen slides being indicated in dotted lines; Fig. 5, a perspectiveview of the springhook removed from the screen, and Fig. 6 a verticalelevation of the left-hand edge of the screen.

A represents the screen; B, the upper window-sash; C, the lower sash,and D and E the strips on which the screen slides.

The screen Ais made of any suitable dimens sions and material and,except as hereinafter described, in the ordinary well-known manner. Toeither side of the casing of the window in which the screen is to beused is fastened a strip of suitable material, preferably wood, andpreferably extending from top to bottom of the window to allow thescreen to be placed in anypcsition therein. The screen is provided, asshown, with a groove D E along each of its edges adapted to engage withthe strips D and E. These strips are 6o also preferably grooved in areverse direction to the grooves in the screen, as shown in Figs.

2 and 4. At suitable points in the groove on one side of the screen (inthe drawings this is shown as the lefthand side, but it may be 65 eitherside, as desired) are placed springhooks F. There may be any number ofthese hooks desired 5 but I prefer to use two. The construction of oneof these hooks is more particularly shown in Fig. 5. It consists of 7otwo rods or shanksff, running substantially at right angles to eachother, and connecting,

as shown, with the portion f, which is preferably flattened. A hole orsocket is bored,

as shown in Fig. 3, in the screen, of suitable shape and dimensions toreceive the shank f', a larger tube or chamber being preferablyconstructed to receive a spring G, which abuts,

as shown, against the inner side of the attened portion f ,forcingitoutward. A plate 8o II is preferably fastened over the hole in thescreen, the spring-hook being provided with shoulders h, contacting withthe inner side of this plate to prevent the hook from being forcedentirely out of the screen by means of S 5 the spring. The plate isprovided with an opening of suitable size to receive and fit theflattened portion f.

At suitable points in the strip D are fastened eyes or sockets I,provided with holes t 9o of suitable dimensions to engage with theportion f of the spring-hook F, there being of course an equal number ofsockets and hooks.

The device operates as follows: To insert the screen the groove D ispassed over the strip D and the screen pressed toward the left. Thisforces in the spring-hooks F, compressing the springs G. The right-handedge of the screen may then be swung around until the groove E comesinto line with the strip roc E. The pressure on the screen being thenreleased, the resiliency of the springs G will force the spring-hooks Fagainst the strip D, carrying the screen slightly toward the right andbringing the groove E into engagement with the strip E. The screen maythen be slid up and down upon the strips D E, and is heldin any positionthrough the pressure of the hooks F against the strip D. If it bedesired to open the screen, it is slid down in the window, the hooks Fengaging as the screen descends with the sockets I. The screen is thenpressed toward the sockets, compressing the springs and releasing thegroove E from the strip E, and may then be swung open, as desired, beingsupported by means of the hooks F and sockets I. One position of thescreen when opened is indicated by the dotted lines in Fig. 2. To closethe screen, press it toward the left sufficiently to allow the groove Eto engage with the strip E, after which the screen may be slid up anddown, as desired. Any other form of spring may be used, as desired, toforce out the hooks F, the flattened portion of such hooks may beomitted, any other suitable guides may be employed in place of thestrips D and E, and other similar changes of form and construction maybemade without departing from the spirit of my invention, the gist whereofconsists in so constructing a screen, door, or similar structure as toenable it to both slide up and down and swing open.

I claimrlhe combination of a screen A, having grooves D and E and hooksforced out by springs, strips D and E, and sockets I, adapted to engagewith the hooks F, whereby the screen may be slid up and down upon thestrips, being held in position by the pressure of the hooks, or, afterbeing pressed to one side to disengage the groove E 'from strip E', maybe swung open, being supported when open by means of the hooks andsockets, substantiallly as described.
